  • Sale
  • Regular price $33.95

Combining maximum security and ease of use like never before, the Black Diamond Magnetron Rocklock uses the power of magnets to reinvent the auto-locking carabiner. Magnetron Technology uses two magnetic arms in the gate and a steel insert in the carabiner's keylock nose to create an ultra-secure, self-clearing and redundant locking mechanism that can easily be used with either hand. Black Diamond's classic RockLock shape is ideal for belaying, making anchors or rappelling, and its keylock nose prevents snagging on slings and ropes.


  • Innovative design uses 2 magnetic arms in the gate and a steel insert in the nose of the carabiner for secure and simple closure; gate can be opened with 1 hand
  • Keylock nose won't snag on pro, ropes or slings, making the carabiner simple to clip
  • Belay loop is held securely in place when carabiner is opened by the square hinge end
  • Slightly curved spine of the Black Diamond Magnetron RockLock locking carabiner maximizes the gate opening
  • Color of gate may vary slightly from online image
